Abstract (en)
A distributed logic control system and communication loop embodies an orchestrater computer (11) containing part of the system logic and a plurality of station computers (13,27, 42, 55, 69) containing part of the system logic. The orchestrater computer and station computers are connected in a communication loop (15, 29, 40, 57, 71, 79). Each station computer controls at least one work station. The orchestrater computer continually time-division multiplexes information packets containing bytes that have different bit setting privileges associated with them. A status byte has assigned privileges, and a command byte and data byte have alterable privileges. The orchestrater computer (11) and any station computer (13, 27, 42, 55, 69) can independently shut down the system prior to failure upon detection of a fault.
